UTG MNT955 ACCU-SYNC Flip-Up Rear Sight AR-15 Picatinny Rail

The UTG MNT955 ACCU-SYNC rear sight delivers precision windage and elevation adjustments for AR-platform rifles. This flip-up iron sight features dual aperture options and tool-free windage adjustment for rapid field corrections.

What Makes This Different

The ACCU-SYNC system sets this sight apart with its synchronized windage adjustment mechanism that maintains zero consistency across multiple range sessions. Unlike standard A2-style rear sights that require tools for windage changes, the MNT955 incorporates finger-adjustable windage knobs with positive click detents. Each click provides 1/2 MOA adjustment at 100 yards, allowing shooters to make precise corrections without removing the rifle from shooting position.

Key Features

• Dual aperture design with large (0.070") and small (0.040") peep holes for varying light conditions
• Tool-free windage adjustment with audible and tactile click detents
• Spring-loaded flip-up mechanism locks securely in both up and down positions
• Fits standard Picatinny and Weaver rail systems without modification
• Aircraft-grade aluminum construction with Type III hard anodized finish
• Low-profile design folds completely flat when not in use
• Same-plane height as military specification A2 front sight posts

Field performance centers on the sight's ability to maintain zero through temperature changes and repeated folding cycles. The spring-loaded detent system provides 140 clicks of windage adjustment range, covering approximately 35 MOA of correction at 100 yards. Competition shooters benefit from the quick aperture selection, while tactical users appreciate the sight's ability to co-witness with red dot optics when folded.
